Sony has updated the Vaio P Series of mini notebooks. Starting at $799, these slim little computers can probably fit in your white coat pocket. The new features include a touch pad (it's really a thumb pad) and a built-in accelerometer. In addition to rotating the screen, tilting the device will also move web pages forwards or backwards (tilt and navigate). I think a "tilt and pan" would be an interesting feature to build into mobile computers. You can read more about the updated Sony Vaio P on Engadget.
